Apple (NASDAQ: AAPL) just started selling the Apple Watch in its physical retail stores, but already the rumor mill is churning about what upgrade to expect in the next version of the company's first wearable device. According to 9to5 Mac, which cited unnamed sources but has a reliable track record on Apple rumors, the Apple Watch 2 will gain a video camera for FaceTime video chatting. The second-generation Watch is also expected to have a new Wi-Fi chipset that will give it more functionality when it is not tethered to a nearby iPhone via Bluetooth. The report said that basic communication tasks could be handled via the Watch without an iPhone connection. Further, the report said that average consumers finish each day with between 30 percent and 40 percent charge remaining on their Apple Watches, and that Apple now believes that it can afford to maintain or just slightly improve the watch's battery life. The next Apple Watch is expected to be released in 2016. Article
